ABSTRACT:
In a round bale forming machine, a twine dispensing mechanism is provided having a twine dispensing arm pivotally mounted on the frame. A spring extends between the twine dispensing arm at one side of its pivotal mounting and a fixation point on the frame at the opposite side relative to the pivotal mounting of the twine dispensing arm. The spring urges the dispensing arm in a first direction away from the rest position, beyond an intermediate position closest to the roll forming region, and to a maximum stroke position. The arrangement is such that during pivotal movement of the dispensing arm from the intermediate position to the maximum stroke position the spring acts on the dispensing arm through a moment arm of increasing length. A rope control is provided to pull the dispensing arm in a second direction opposite to the first direction induced by the spring, and towards the rest position. A latch automatically latches the dispensing arm in the rest position.
